Abstract: A method for capturing screen content of a mobile terminal and a device thereof are provided. The method comprises: detecting a DOWN event of a specified key of the mobile terminal and recording the time of occurrence of the DOWN event as a first time stamp; detecting an UP event of the specified key and recording the time of occurrence of the UP event as a second time stamp; and comparing a difference between the second time stamp and the first time stamp with a preset time threshold, performing a full screen capturing or a regional screen capturing on the screen content of the mobile terminal if the difference is less than the preset time threshold, or performing a regional screen capturing or a full screen capturing on the screen content of the mobile terminal if the difference is greater than the preset time threshold.
